FAQs
Install as a three-pole, three-wire disconnect with line and load connections to the appropriate terminals. Use the 200 A rating and 600 V maximum, select Class H fuses, and wire with conductors from #6 AWG to 300 kcmil. Ensure proper mounting in a NEMA 4X rated enclosure and verify the voltage indicator visibility on both line and load sides.
The DD364FWKW-00V3 is rated for 200 A, 600 V, and uses Class H fuses. It is fusible without neutral and offers three-pole, three-wire configuration for robust three-phase protection.
Yes. It is rated at 600 V and supports three-phase applications, with HP ratings up to 50/125/150 hp (1/3PH at 480/600 V), making it suitable for motors and drives in 480 V systems.
The unit is UL Listed and housed in a NEMA 4X enclosure constructed from 304 stainless steel, providing superior corrosion resistance and suitability for washdown environments.
The rugged stainless enclosure and durable fuse configuration reduce field maintenance and nuisance trips, improving uptime. With UL listing and a robust 304 stainless build, organizations typically see lower lifecycle costs and safer, more reliable panel protection; warranty terms include one year from installation or 18 months from shipment, whichever occurs first.
